Impossible is possible, or How to assemble a Rubik's cube 5x5

Rating of a popular toy created by ErnoRubikom, grows all over the world. The number of combinations of the cube assembly is an unimaginable number of 43 quintillion. But to collect it is real, even if you never took it into your hands. Professional speedcubes know how to collect a Rubik's cube 5x5 in a few seconds.

Getting to know the puzzle

So you decided to buy yourself such a toy. Congratulations on buying a Rubik's cube 5x5! It is also called the Professor's Cube. Now, for sure, you want to learn the way of assembly, which would not consist of complex and intricate schemes. But in order to understand how to collect a Rubik's cube 5x5, you need to get acquainted with the device of the puzzle.

The cube consists of cubes of smaller size, eachan edge - a row of five such small cubes. All layers of the puzzle can rotate independently, regardless of other layers - it is thanks to this that the components can be rebuilt on the surface of the cube.

Each of the six faces is represented by its colorso that the corner pieces include three colors, the edge - two colors. In turn, the central part of each face is the same color and, like in the classic 3x3 Rubik's cube, never changes its position, because it is fixed by a skeleton.

So, the Professor's cube consists of: centers, edge centers, corner centers, outer edges, the edges of the center and corners. This complicated mechanism was patented by Udo Krell on July 15, 1986.

How to collect a Rubik's cube 5x5: the variety of ways

No matter how difficult the Rubik's cube 5x5 seemed, inOur time there are several methods of assembly. Moreover, the volumes of schemes and formulas that are suggested to remember determine the speed of assembly: the more of them, the more the number of moves decreases in order to achieve the desired result. We present to your attention three methods for solving the puzzle:

1. The solution of the problem reduces to mastering a simplera cube of 3x3. This method is recommended for those who already have experience with puzzles. The first thing is to assemble the centers, then assembly the edges, from it go to the assembly of the last two edges and parities. This completes the new formulas, because the Professor's cube is going on in the same way as the 3x3 cube.
2. We collect a cube from the top layers to the bottom one. It should be noted right away that this method is good, but for a 5x5 cube it is too long and inefficient.
3. Assembly is carried out from corners. The essence of the method is that the upper and lower corners are collected first and only after that go to the ribs and the remaining centers.

How to collect Rubik's Cube? Scheme for beginners

For your first solution this puzzle is betterjust use a detailed scheme that will visually and step by step explain how to collect a Rubik's cube. For beginners, this scheme will contain a large number of moves. However, we present to your attention a technique that has a relatively small number of moves and is not difficult to learn and understand.

It is based on the way that was developedin the eighties and published in the journal "Young Technician". It was slightly optimized and simplified for mnemonic memory. With training in memory, all formulas are printed, and if you want to collect a Rubik's cube, you will not need a diagram.

The most common mistake of newbies: very many collect only one side and believe that now they will be able to collect all the others in the same way, but they immediately notice that the adjacent cubes do not take their place, and when they try to shift their harmony they are violated.

How to collect a Rubik's cube 5x5, presented inThis optimal and accessible algorithm: the centers of the upper face, the upper angular centers, the lower angular centers, the lower edge centers, the upper corners, the lower corners, the edges of the lower face without one of the edges, the ribs of the upper face, the final stage of the assembly of the edges of the lower face, the lower and middle faces, upper and middle ribs, mid-rib centers, lateral corner centers and, finally, lateral middle centers. This method is much simpler and clearer in the pictures.

Speedcubing: what is it and what are its advantages

If you are wondering how quickly to assemblecube-rubik, then you need to master the technique of speedcubig - the fastest assembly. Its feature is a large number of schemes for the different positions of the constituent cube. It is thanks to the variety of formulas that the assembly speed increases to several seconds.

Great popularity among the speedcubesuses the method of Jessica Friedrich. There are even competitions that are regularly held by the WCA, at the world level, where participants compete with each other in speed assembly. To date, the official record of the assembly is 48.42 seconds.

A little about the creator of the Rubik's cube. Interesting facts about the puzzle

Erno Rubik in Hungary is known as a sculptor,inventor and professor of architecture, and world fame he got thanks to the puzzles and toys he created. Among them is the famous Rubik's cube. Now he is seventy years old, but he continues active in architecture, is the head of the studio Rubik and in cooperation develops video games.

Rubik's cube is considered the leader in sales amongall toys. If we calculate all the sold original modifications and analogues and put them in one row, then its length will be equal to the distance between the poles of the Earth.

Puzzles over how to collect a Rubik's Cube5x5? Computer technology went further. Similar Rubik's cube puzzles are modeled in programs. The developers did not stop at the sizes 2x2 or 3x3; in computers they place four, five or even seven-dimensional analogues impossible in the physical world - cubes per 100x100 or even 1000x1000 cubes!
